Snap for 8512216 from d9b77fd7cfd092afd5776b062fb2de36ba7c5218 to tm-frc-scheduling-release Change-Id: I521952bbad12c307bdfce354f3737aed68a8ed8c
Determine if a char
is a valid identifier for a parser and/or lexer according to Unicode Standard Annex #31 rules.
extern crate unicode_xid; use unicode_xid::UnicodeXID; fn main() { let ch = 'a'; println!("Is {} a valid start of an identifier? {}", ch, UnicodeXID::is_xid_start(ch)); }
unicode-xid supports a no_std
feature. This eliminates dependence on std, and instead uses equivalent functions from core.
